Referring to said drawings, A is the elevated track upon which the two carriages, B

and C, travel. Said track is usually a horizontal cable secured by its ends to fixed objects at suitable elevations.

The carriage, B, has two grooved wheels or rollers, B Each of said wheels loosely surrounds a spacing tube, 13 A bolt, B extends through the spacing tube.- At each side of the pair of wheels is a horizontal channel. bar, 13*, which is penetrated by one of the bolts, B At each side of theleft hand wheel, as viewed in the drawings, a bar, B, is located between the wheel and the channel bar, B. The adjacent bolt, B also penetrates the bars, B Bars, B, are similarly applied between the righthand wheel, B and the bars, 13, and are similarly penetrated by the bolt, B and a spacing tube, 13 surrounds said bolt. The lower ends of the bars, B and B over-lap each other and are penetrated by a horizontal bolt, B", the forward bar, B over-lapping the forward bar, B

the rear bar, B over-lapping the rear bar,

B and said bars forming a pair.

A clevis, B is also applied to the bolt, B, one eye ofthe clevis being at the outer side of each pair of the overlapping bars, B and B The eye, B, of a swivel block, B rests be- Said clevis is directed toward the left.

and said bars forming a pairfand' I tween the pairs of bars, B and B and is penetrated by the bolt, B7. Thus said bolt is made to support said block. At the front and at the rear of the carriage an upright bar, B is suitably secured to the adjacent horizontal channel bar, B", and the oblique bars, B and B. Two grooved rollers, B are placed one above the other between said bars and supported on horizontal bolts, B. The function of said rollers is to support and guide the cable, G, as will be described farther on. The function of the swivel block, B is to support and guide the loadline, H, to be described farther on. The function of the carriage, B, is to support and carry the rollers, B and the swivel block, B

A clevis, B is coupled to the diagonal bars, B, by means of a horizontal bolt, B extending through the elevis and said bars.

A butler block, B is placed between the right hand ends of the channel bars, B and is secured in position by the horizontal bolt, B extending through said bars and said block.

Immediately below each roller, B a roller, B is placed between the diagonal bars, B and B and is there supported by a transverse bolt, B. For convenience, the carriage, B, will be termed the load carriage.

In the carriage, C, the wheels, C the channel bars, C, the bolts, C the spacing tubes, C the diagonal bars, C and U, and the bolt, C correspond, respectively, to the parts, B to B inclusive, in the carriage, B.

Below and parallel to each channel bar, C, a channel bar, C extends from the adjacent bar, C to the adjacent bar, C, and has its ends suitably secured to said bars. At the front and at the rear an upright bar, C, has its lower end forked and suitably secured to the adjacent bars, 0' and C, and extends upward along the inner tace ot the adjacent bar, C A grooved roller,C is located between the bars, C opposite the bars, C A horizontal bolt, C penetrates the bars, C and C, and the roller, C and a spacing tube, C located within the wheel.

Abovesaid roller, a bolt, C extends horizontally through the two bars, C", and is surrounded by a loose tube, C

i\ (iltlll'lpl1lg block, C is placed between the lower ends of the pairs of diagonal bars, C and C. Screw bolts, C extend horizontally through the o\"erla )ping ends of each pair of diagonal bars into the clamping block. Thus the clamping block is supported to permit rocking on the journals formed by the screw bolts. In the upper faceot-and parallel to the length of the clamping block is a channel, C Said channeli's of proper width and depth to allow the load line, H, to lie therein with its axial line approximately cutting the axial line of the screw bolts, C Two U-bolts, C extend across the load-line, H, and have their arms extending downward through the clamping block. Said U-bolts firmly clamp the load-line into the groove, C lVhen the nuts on the U-bolts have been loosened, the 1oadline may be shifted endwise in the clamping block.

A buffer block, C similar to the buffer block, B is similarly applied to the left hand ends of the channel bars, 0 of the carriage, (l, by means of a'bolt, C Said buffers are intended to meet and receive shock when the carriages are accidentally brought together.

A roller, C similar to the rollers, B of the carriage, B, is placed below each wheel, 0 and between the bars, C and C, and supported by bolts, C extending through the bars and rollers. F or convenience, the carriage, C, is termed the clamp carriage.

The drums, G F and H shown in diagram on the drawings, are conveniently located, in the well-known manner, for controlling the different cables or lines 'tOlnling a part of the apparatus.

The load-line, H, extends upward along the left of the swivel-block, B and then rightward over said block andthrough the clamping block and then over guide rollers, H to the load line drum, H A load carriage cable, F, extends from the clevis, B to the load carriage line drum, F A clamp carriage cable, G, extends from the clevis, B rightward to and around the roller, C and thence leftward between the rollers, B, of the carriage, B, and thence to the clamp carriage line drum, i

The operation is as follows:

Let it be assumed that the carriages are on the track, A, at any desired distance rightward of the drums and that the carriages are separated to bring the free end of the load line above the ground, and that said end of the line is to be lowered to receive a load either directly under the track or a short distance or several hundred feet sidewise from the track. v f

To lower the free end of the load-line into position to receive the load, the carriages are drawn toward each other by winding the cable, G, on the drum, G and allowing the cable, F, to'unwind from the drum, F the drum, H being held stationary. Thus the carriage, B, is moved toward the carriage,

'(l, and during such movement the loadline passes leftward through the swivelblock, B.

When the load has been attached to the load-line, H, the carriages'are to be sepa rated until the load]ine, H, has been drawn eightward through the swivel-block far enou-ghto lift the load to the desired height. Then the two carriages are to beheld at the same distance from each other and moved simultaneously to the left along the track, A, until the point for discharge of the load has been reached. The separation and simultaneous movement of the carriages are effected by causing the drum, H to wind the load-line and at the same time allowing the drums, F and G to unwind, brakes being preferably applied to the drums, F and G in order that the cables, F and G, may remain under sufficient tensionto avoid slack in said cables.

hen the point for discharge has been reached, the load may be released While it is in its elevated position or the load may be lowered by holding the drum, H releasing the drum,- F and turning the drum, G whereby the winding of the cable, G, on the drum, G will draw the carriage, B, toward the carriage, C, until the load has been brought as low as is desired.

It is to be observedthat the shape of the carriages is such as to keep the swiveled block of the load carriage separated from the clamping device of the clamp carriage even when the carriages bear against each other. This is eliected by the horizontal members, 13*, of the load carriage and the horizontal members, C of the clamp carriage. Furthermore, at such time, the load butler, B flon the load carriage bears against the buffer, C of the clamp carriageand thetwo butters form a swivel or rocking point, whereby the load carriage is made free to swing sidewise, independently of the clamp carriage, when the free end of the load line is to be taken sidewise a short distance or several hundred 'feet to get aload. It must be observed that in such case it is desirable to have the load carriage turn from the upright to the same inclinedposition as the load linetakes to reach its load. And in this connection it must beremembered that the two carriages are to be brought together when the load line is to be let out to approximately its maximum length;

As is already well-known in this art, the drums are to be provided with friction brake or clutch mechanism allowing slipping when there is excessive strain, in order that when alimit of movement of the carriages or the load is reached, such slipping will avoid damage to the mechanism. a

It is to be observed that each of the cables, G and F, has both its ends secured in such manner as to avoid twisting'of the cable during the operation of the apparatus, and that the part of the load-line'between the drum, H and the clamp, C issimilarly held against twisting. Thus these lines are not duringoperation put into such twisted conditionas will cause kinking-the douiblingancl t ist ng upon each other f p rts of the cables. In the operation of similar apparatus, in which the cables are not held against twisting, serious delays and sometimes derangement and breakage of the apparatus result from such twisting. Time lost and the replacing of damaged parts make large loss items.

The rollers, B and C serve to prevent the carriages from rising on the track cable, A.
